Two lines have the following equations

Mashcka [7]

Answer:

(4,-3)

Step-by-step explanation:

Easiest way to do this without any advanced methods is to use the answer choices to your advantage.

For a.) we have (1,1) meaning x = 1 and y = 1 if we get a 7 for the first equation and a -2 for the second equation then that is the correct answer.

Let x=1, y =1:

4(1)+3(1)=4+3=7 Correct so far.

1+2(1)=1+2=3 Incorrect since we should have got a -2 if this was the solution

Let (0,-1) x = 0, y = -1:

4(0) + 3(-1) = 0 -3 = - 3 Incorrect so we can stop there next answer choice.

Let (4,-3) x = 4 y = -3:

4(4)+3(-3)=16-9=7 Correct so far.

4+2(-3)=4-6=-2 Both are correct!

Therefore the solution (where the lines intersect) is (4,-3).

Dose anyone have the answer to this question

Anuta_ua [19.1K]

Answer: (A) SAS (B) No (C) SSS (D) No

<u>Step-by-step explanation:</u>

A) ET ≅ MT, ∠T ≅ ∠T, TA ≅ TA ⇒ Side-Angle-Side

B) top and base are congruent, diagonal is congruent to itself, but there is no way to prove that two angles are congruent without knowing if either of the sides are parallel.

C) JU ≅ JE, UN ≅ EN, JN ≅ JN ⇒ Side-Side-Side

D) angle-angle-angle only proves similarity, not congruency

How can we factorise the expression: 2x^6+17x^3+8?

LekaFEV [45]

Answer:

$(a + 2)( {a}^{2} - 2a + 4 )(2 {x}^{ 3} + 1)$

Step-by-step explanation:

$2x^6+17x^3+8 \\ = 2x^6+16x^3 + {x}^{3} +8 \\ = 2{x}^{3} ( {x}^{3} + 8) + 1( {x}^{3} + 8) \\ = ( {x}^{3} + 8)(2 {x}^{ 3} + 1) \\ = ( {x}^{3} + {2}^{3} )(2 {x}^{ 3} + 1) \\ = (a + 2)( {a}^{2} - 2a + {2}^{2} )(2 {x}^{ 3} + 1) \\ = (a + 2)( {a}^{2} - 2a + 4 )(2 {x}^{ 3} + 1) \\$
